Source: Xem Studio, https://xemstudio.com/objects/washers-clevis-pins-din-1440/  (sheet CC BY 4.0)
Basis: McMaster-Carr's DIN 1440 table (d1, d2, s), cross-checked size by size against ehorst plus Keller & Kalmbach, Würth, Galaxus and Dinmark listings
Catalog version: 2026-10-20

Sizes: see table below
- Columns: pin diameter (= bore d1), outside diameter d2, thickness s. These are the DIN 1440 sizes as sold; the replacement ISO 8738 (DIN EN 28738) uses smaller outside diameters for several sizes (e.g. 12 mm pin: 20 instead of 25), so the two are not interchangeable.
- Pin 7, 24 and sizes above 32 are omitted (single source or conflicting values). Edges drawn sharp.
